psychosocial development,

(in child development) a description devised by Erik Erikson of the normal serial development of trust (birth to 12 months), autonomy (1 to 2 years), initiative (3 to 5 years), industry, identity (12 to 18 years), intimacy, generativity, and ego integrity (60s and above). The development begins in infancy and progresses as the infantile ego interacts with the environment. For the child to reach a new stage successfully, the tasks of the preceding one should be fully mastered.
